Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16
Answer:
y=2x+3
Step-by-step explanation:
Use the equation: y=mx+b
m is the slope (2 in this case)
b is the y intercept (3 in this case)
So the equation of the line would be y=2x+3
Yes they are right. 2+784
Answer:
The total surface is 48 ft
Step-by-step explanation:
Answer:
141
Step-by-step explanation:
Area of a trapezium =
(a + b)
h = height
a and b = upper and and lower lengths
Area of a trapezium =
(10 + 16)
=
× 26
= 117
Area of a triangle =
× base × height
=
× 6 × 8
=
× 48
= 24
Total area = Sum of the areas of both the shapes
= 117 + 24
= 141
